4. Batch Processing Workflow

import os, json, datetime
from pathlib import Path

def organize_invoices(input_dir: str, output_dir: str):
    """
    Process all PDFs/images in input_dir:
    1. Extract data from each file
    2. Rename to standard format
    3. Move to output_dir/YYYY/Category/
    4. Return summary CSV
    """
    results = []
    for file in Path(input_dir).glob("**/*"):
        if file.suffix.lower() not in ['.pdf', '.png', '.jpg', '.jpeg']:
            continue
        
        # Extract (using Claude vision or PDF parser)
        data = extract_invoice_data(file)
        
        # Build new filename
        new_name = f"{data['date']}_{data['vendor'].replace(' ', '-')}_{data['amount']}-{data['currency']}_{data['category'].replace('/', '-')}{file.suffix}"
        
        # Destination: output/2025/Software/
        dest_dir = Path(output_dir) / data['date'][:4] / data['category']
        dest_dir.mkdir(parents=True, exist_ok=True)
        
        # Move file
        new_path = dest_dir / new_name
        file.rename(new_path)
        
        results.append({**data, 'new_path': str(new_path)})
    
    return results

6. Rules

• Never delete originals: Rename and move, always keep backup of original
• Flag ambiguous items: Don't guess category for unusual expenses — mark as "Review"
• Currency conversion: Record in original currency + USD equivalent at date of purchase
• Receipts vs invoices: Receipts = proof of payment; Invoices = request for payment (both needed for audit)
• Retention: Keep all tax-related documents for 7 years (US IRS standard)
